Slow Rotor

Hey guys it seems i did an apex seal the other week and while its away im considering getting it extend ported and dowelled, what are the advantages/disadvantages of it i know its gonna give me more power and make a motor that can take more boost thats about it. Im not going for the 3mm seals i just want some 2mm race ones i figure when the housing wears i will just go for the 3mm then.
